All you would do is put 23 in the box and put -5 outside and solve
I mean it could be read that way but that's the way most people read fractions. 11 and 8/10. Most people I know read decimals like that as 11 point 8. So yes I suppose it's true; it's not wrong, but most people don't say it like that. And I don't know how they taught you to read it in your math course.
Using proportions, it is found that Demarco needs 4 tiles.
----------------------
- This question is solved by proportions, using a rule of three.
- Each tile uses 1/2 = 0.5 ft.
- In total, he needs 2 ft.
Thus, the<u> rule of three</u> is given by:
1 tile - 0.5 ft
x tiles - 2 ft
Applying cross multiplication:
Thus, Demarco needs 4 tiles.

B) is correct; on average, each bag of candy has a weight that is 2.6 oz different than the mean weight of 5 oz.
To find the mean absolute deviation, we first find the mean. Find the sum of the data points and divide by the number of data points (without the outlier, 21, in it):
(10+3+7+3+4+6+10+1+2+4)/10 = 50/10 = 5
Now we find the difference between each data point and the mean, take its absolute value, and find their sum:
|10-5|+|3-5|+|7-5|+|3-5|+|4-5|+|6-5|+|10-5|+|1-5|+|2-5|+|4-5| =
5+2+2+2+1+1+5+4+3+1 = 26
We now divide this by the number of data points:
26/10 = 2.6
This is a measure of how much each bag of candy varies from the mean.
Answer:
X+4=Y
So lets look at the first one,
X=0
So 0+4=4
So Y=4
